postprocess: call restrict_dead_end_edges_here()
Related to issue #587. * spot/twaalgos/postproc.cc, spot/twaalgos/postproc.hh: Add support for option "rde". * bin/spot-x.cc, NEWS: Mention it. * tests/core/deadends.test, tests/core/ltl2tgba2.test, tests/python/atva16-fig2a.ipynb, tests/python/deadends.py: Adjust test cases to reflect the improvement. * tests/core/ltlsynt.test: Also adjust this test case, which is the only one worsened. Some extra gates are generated when translating GFa<->GFb with --algo=ds or --algo=sd. Issue #588 would be one way to fix that.
